Chicken guillotine

Chicken guillotine

In past years we just always did the ring-the-neck-and-flop method of killing chickens. Wondering if there might be a better way.

I've ordered some cones. That's a start.

So I'm reading 'The Have-More Plan' copyright 1973. On page 33 it shows a device that looks like a tiny chicken guillotine, but it doesn't give
the device a name, and just says "A light blow of the hand and blade, held steady in the slot, punctures spinal cord leaving outlet for blood. Blade snaps
back."

Google doesn't seem to have ever heard of the device (or they're too politically correct to admit it). Anyone know where to get one of these?
